Runtime Memory Optimization - freeradius2 for OpenWRT

Hi, I recently compiled freeradius2 for OpenWrt attitude adjustment, did selective compilation of freeradius2 only with EAP-TLS module since I want to use only this module. I am facing two issues, Can someone help me over this. 1. Freeradius2 is taking 3.7 MB RAM runtime memory on OpenWRT board, Can we further optimize/ reduce runtime memory requirement on OpenWRT. 2. Freeradius2 is not starting without debug mode. Any input/ pointers would help. Thank you. Regards Lalit
